FRANKLIN A. DEAN AND LEWIS L. TEAS, OF ALTA VISTA, KANSAS.

AUTOMATIC COPY-HOLDER.

Specicaton of Letters Patent.

Patented Apr. 21, 1914.

T0 all whom it may concern:

Be it known that we, FRANKLIN A. DEAN and LEWIS L. TEAs, citizens of the United States residing at Alt-a Vista, in the county of Wabaunsee and State of Kansas, have invented new and useful Improvements in Automatic Copy-Holders, of which the following is a specification.

This invention relates to automatic copy holders, applicable to typewriting machines, t-he object in view being to provide a copyholder capable of being mounted on any standard typewriting machine, and embodying a revolving platen similar to the platen of the typewriting machine, the same being connected with the carriage of the typewriter, and operatively connected with the shaft of the machine platen, so that the platen of the copy-holder is not only fed along with the machine platen, but is simultaneously revolved therewith.

A further object of the invention is to provide means whereby the platen of the copy holder may be set, so that the matter to be copied may be arranged to register with the matter being written.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the accompanying drawings: Figure 1 is a front elevation of the copy-holder shown applied to the frame of a typewriting machine. Fig. 2 is a plan view thereof. Fig. 3 is a vertical cross section through the copyholder. Fig. t is a front elevat-ion of the supporting frame and a portion of the carriage of the copy-holder, said view being partly in section. Fig. 5 is a detail perspective view of the gear shifter.

Referring to the drawings, 1 designates the frame of a typewriting machine, upon which the copy-holder is mounted. The frame of the copy-holder comprises a pair of supporting standards 2 connected by a cross bar or brace 3 and provided with forwardly extending feet 4 which are secured to the typewriter frame 1 by means of screws 5, or their equivalent. The standards 2 are of suitable height to support the copyholder at a convenient elevation, and the upper ends thereof are connected by means of upper and lower track rails 6 and 7, re-

spectively, secured to the standards by screws 8 or other fastenings. @perating between the track rails-6 and 7 are upper and lower carriage rails 9 Yand 10. The upper pair of rails, as well as the lower pair cf rails, are provided in their adjacent faces with grooves 11 and 12, in which are arranged anti-friction balls 13 forming a rolling support for the carriage of the copyholder, and enabling the same to move back and forth with the least possible friction.

The carriage of the copy-holder comprises forwardly projecting brackets 14, in which is journaled the shaft of a revolving platen 16 faced with rubber, similarly to the platen of the typewriting machine, and around this platen paper, indicated at 17, is adapted to pass, the paper being sustained by means of a paper support 18.

19 designates a pair of paper guides arranged over the platen 16, and 2O designates a centrally arranged pointer which is fixedly secured by means of a screw 21 or its equivalent to the lower track rail 7 of the copyholder.

The platen 16 of the copy-holder is adapted to move lengthwise simultaneously with the machine platen 22 by means of one or more shifter arms 23 connected at their upper ends to the lower carriage rail 10 and having at their opposite ends forks 211 which embrace the end portions of the machine platen 22, as illustrated in Fig. 3. Therefore, as the machine platen 22 is fed along with the carriage of the typewriter, the platen and carriage of the copy-holder are simultaneously fed along at the same speed, so that the fixed pointer 20 is adapted to indicate the exact word or letter being imprinted upon the paper on the machine platen 22. On one end of the shaft of the platen 22 is fastened a beveled pinion 25 meshing with another beveled pinion 26 on the lower extremity of a vertically movable shaft 27. This shaft 27 has at its upper end another pinion 28 meshing with the pinion 29 on the adjacent end of the shaft 15 of the platen 16.

30 designates bearing brackets for connecting the shaftsadjacent to their opposite ends.

The shaft 27 is held normally depressed by means of a spiral spring 30 extending around the shaft and interposed between the upper bracket 30 and a fixed collar 32 on the shaft. This holds the pinions referred to normally in mesh, but they are adapted to be thrown out of mesh by means ofya rotatable sleeve or collar 33 surrounding the shaft 27 and bearing on the lower bracket 30 as shown in Fig. l. The sleeve or collar 33 is provided with a milled iiange 34 to facilitate turning the same by hand and is also provided with one or more inclined shoul ders 35 which cooperate with a corresponding number of pins 36 on the shaft 27 so that by turning said collar 33 the shaft 27 may be raised to throw the pinions out of mesh. rlhe mechanism referred to provides for the corresponding simultaneous turning of the two platens when either one thereof is ma` nipulated and also provides for setting the two platens in such relation to each other that the matter to be copied will correspond with the matter being` written upon the paper surrounding the platen of the machine. It will now be observed that by holding the platen Q2 stationary and turning the platen ltby means of the usual milled hand wheel 37, the copy may be brought into register with the matter being imprinted upon the paper on the machine platen.

From the foregoing description, it will be understood that as the platen of the typewriting machine travels back and forth, the platen of the copy-holder is correspondingly moved equally therewith. It will also be understood that when the platen of the typewriting machine is turned, the platen of the copy-holder will be correspondingly turned by means of the gearing described. Furthermore, the platen of the copy-holder may be turned independently of the platen of the typewriting machine for primarily setting the printed matter carried by the platen of the copy-holder to register with the printed matter on the sheet carried by the machine platen. The copy holder supports the copy in a convenient position above the platen of the typewriting machine, and a little in rear of the vertical plane thereof.

lVhat is claimed is:

l. A copy-holder for typewriting machnes, comprising in combination with the machine frame and platen, a stationary supporting frame extending upwardly from the machine frame behind the machine platen, a rotatable copy platen mounted to move with the machine platen and supported by the frame of the copy-holder, a gear wheel on the shaft of the copy-holder platen, a gear wheel on the shaft of the machine platen, a driving shaft movable into and out of gear with said wheels, and a spring yieldingly holding said driveshaft in gear and permitting it -to be thrown out of ,gear without moving the copy-'holder platen.

2. A copy-holder for typewriting machines, comprising in combination with the machine frame and platen, a stationary supporting frameextending upwardly from the machine frame behind the machine platen, a rotatable copyfplatenmounted to move with the machine platen and supported by the frameof the copyfholder, gear wheels on the shafts of both platens, a carriage for the platen of the copy-holder movable along said copy-holder frame, and a slidable drive shaft adapted to be shifted into and out of gear with said wheels without moving either platen.

3. A copy-holder ,for typewriting machines, comprising in combination with the machine platen a rotatable platen mounted to move with the machine platen, a gearwheel on thezplaten shaft of the copy-holder, a shaft drive from said gear wheel to the machine platen shaft, a shoulder on the drive shaft of the copy-holder, a sleeve having an inclined. shoulder cooperating with said shoulder on the shaft to throw the latter out of gear, and a spring acting to throw the shaftback in gear.

In testimony whereof we aiix our signatures in presence of two witnesses.
